Vertical Bars on Laptop Screen

[veronicak5678]

I have a Compaq Presario r4000 that was dropped. Since then, the right side of the screen has a band of vertical stripes, about 4 inches wide and running from the top to the bottom. I plugged it into my desktop monitor and the picture looked fine, so I figured the screen had to be replaced. I got a new screen with a new video cable and inverter board and installed. I just turned it on to see the same thing happening. What can I do?

Well, from the first sight, you could have seen it was a graphics card issue. Well this might happen due to hard shocks....

Just wipe out that graphics card and get a new one.

Thanks for answering. From everything I read and the advice from a few people on various forums, I was sure the screen had to be replaced. No one ever mentioned a graphics card. Is it easy to replace the graphics card? I have never really worked on laptops before.
